This is bad. This is very bad. Trump wants to start "testing" nukes again.
www.bbc.co.uk
Trump says nuclear weapons testing to resume in US after more than 30 years
It is necessary for the US to keep pace with weapons programmes in China and Russia, the president says.

I've seen it so many times now that I no longer need my DVD. it's on permanent loop in my head. I can recite along with the lines like an old episode of Red Dwarf.

Have you ever wondered why all TV studios suddenly switched from tape to HDD servers for VT at the same time?
...Ok, maybe you haven't.
It was because the only factory in the world that made Sony digi beta tape was in Fukushima.

I have a mate who worked for Meridian TV in the late 90s early 00s.
His big job new years eve 1999 was to sit at a desk at wait for midnight. IF the millennium bug did take hold, was to flick a switch and turn on the emergency broadcast. £3500 he got for that night.
Anyway, he claims he found the tapes made by the Queen and his Tonyness the Blair incase the balloon went up and Russia decided to nuke.

Some 6am musings before I retire:
Back in the late 90's, when my grandparents finally sold their metroland ... mansion, tbh, to my cynical, "could have had a shot at inheriting that maybe in my dreams" memories... ahem.... and moved to a bungalow in the middle of nowhere in Dorset...
Naturally, being next to what they claimed was the largest single field in England, their new place was rather remote, and utterly black at night compared to the west London light pollution they (and, indeed, I) were used to.
But not to fear, for my grandad had a solution! In the form of these little thumb sized clear acrylic .... excuse my turn if phrase.... nubbins .... placed at the top handle-side corner of every single door frame in the house, on both sides.
Did I mention that whatever was inside these ... things... glowed with an "eerie green glow" 24/7/365, nomatter how long it has been since it last saw an external source of photons?
...
Yeah, just suddenly wondering how irradiated they got in their final years from what I only just remembered, and realised were almost certainly some kind of radium source.
I don't think I spent more than a cumulative total of three months over five years in that house, so I'm not worried for myself. But I do have to wonder. Are they still there? Is the new owner of that property still enjoying those magical "your door is HERE" glowlights?
The acrylic was pretty thick, and the glowy bit inside was tiny. So I'm not too worried. Although the acrylic dome had a lens effect that made it look bigger. I know because I had what is now, as I think about it, more that one scarily very close look at them. As in, putting my eye right up to them in the middle of the night trying to work out how they were still glowing.
I mean, my god, I wasn't an idiot. I was top tier for GCSE sciences, double A grade. Even back then, I had my interest in all things nuclear. I knew about the radium dial girls. Yet somehow, I never put the screamingly obvious together! Maybe the "oooh, pretty lights!" part of my brain was overriding the logical part? Would make sense... that was about the age I was starting to get into lighting.
.... But still!
... (yes, I shall go to bed now. If I can sleep after this realisation.)

All that luminous body paint we used to mess with as kids in the sixties...Then suddenly you could only get the boring "black light" stuff...nothing like as good!
I did wonder why it vanished.
Do you think I am safe in my Beach glow in the dark Ghost Train long sleeved tee's?
I do have three, wear them all the time...
Can I sue?

Sound to me like they're probably tritium lights, which are still very much a thing and pretty awesomeSome 6am musings before I retire:

They're small glass vials containing tritium gas, a beta radiation emitter (i.e. emits electrons). The vial is then coated internally with phosphor (a-la fluorescent tubes), which glows when the electrons hit it. Often then encased in acrylic.
Half life of Tritium is a bit over 12 years, so every 12 and a bit years the luminosity halves... but still means they glow for decades!
Beta decay is very easily absorbed by most things, so the glass vial alone stops emission - sorry D! Buuuut best not to break them lol.
Still perfectly legal in many places - quick search of Amazon will show you loads of zip tags and the like!
